The mathematical modelling and optimization of nonlinear problems arising in diversified engineering applications is an area of great interest.The Hammerstein structure is widely used in the modelling of various nonlinear processes found in a range of applications.This study investigates the parameter optimization of the nonlinear Hammerstein model
The yield of three disinfection byproduct formation potentials (DBPFPs), including trichloromethane, dichloroacetic acid and trichloroacetic acid formation potential (TCMFP, DCAAFP and TCAAFP), by Microcystis aeruginosa under the nitrate and phosphate inhibition conditions was investigated.The GF COCONUT SHRED UNSWT results showed that excessive ni
Gastrointestinal manifestations of COVID-19 are rare and have primarily been limited to diarrhea or vomiting.Intussusception is the most common cause of bowel FLORAVIT YEAST obstruction in infants, with up to 30% of pediatric intussusception cases having a preceding viral illness.We present the rare case of intussusception in a SARS-CoV-2 positive
In this paper, a unidirectional positioning stage which is supported by four Contraceptives coil-type spring isolators and actuated by four pneumatic cylinders is considered.The stage jerk feedback scheme (SJFB) with positive polarity is proposed to reduce the stage mass, resulting in the improvement of positioning speed.However, reduction of stage
